PAPHER-SCORING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 267,849, dated November 21, 1882,

' ApplioationfiledMay 5,1882. (ModeL) To all whom it may concern:

Be it known that I, ALBERTE. ELMER, of Springfield, in the county of Hampden 'and State of Massachusetts, have invented a new and useful Improvement in PaperScorin g Machines, of which the following is a full, clear, and exact description.

This invention relates to a machine for formin gthe scores or breaks in sheets of strawboard or other paper preparatory to bending the sheets for forming paper boxes or for other purposes. 4

Reference is to be had to the accompanying drawings, forming a partof this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation, partly in section of my new andimproved scoring-machine. Fig. 2 is a sectional elevation of the same, taken on the line was of Fig. 1 and Fig. 3 is a plan view of one of the cam-wheels used for reciprocating the compressing head or bar of the machine.

A Arepresent the cam-wheels, which are secured upon the ends of the main shaft B, which ing-head is secured in the main frame the crosspiece F, which is formed or provided with the rib f, upon which the sheets of paper or other material are scored or broken by being pressed over and upon the rib by means of the compression-head D being brought forcibly down upon'them. To prevent the material being cut or injured from being compressed between the rib and compression-head, and to cause the machine to make a good and perfect score in the material, I provide the face of the compressionhead with the strip of rawhide or some other yielding material, G, which forms the contactsurface of the head with the material being scored. Thisyieldin g material is placed in the recess 6, formed in the compression-head, and

is held in place by the plate 9 and screws or other fastenings i, and the yielding material may be adjusted in the recess by means of the elongated screw-openings a",'formed through the same, through which the screws pass.

The cam-gutters a a of the cam-wheels A A are by preference formed with the two (though one may be used with good effect) inwardlyprojecting swells or steel cams jj, situated at that part or portion of the gutters which comes nearest the shaft, which swells or cams cause the compression-head at the time it comes in contact with the material being scored to have two sudden and distinct downward movements or thrusts. One of the swells or cams-j',i'or example--is madelarger than the other, so that the second downward movement of the com- ALBERT E. ELMER, OF SPRINGFIELD, MASSACHUSETTS, ASSIGNOR TO WILL- pression-head willbe'greater than the first. By 7 the slots 71. h, (at both ends of the table,) through which the bolts is k, which hold the guide or stop npon'the table, pass for the adjustment of the saidguide or stop. In front of the crosspiece F is placed, in the main frame, the table H, which has hinged to its forward edge the leaf K, which has secured to its under side the springs Z l, which support the leaf, so that its upper edge-will come about on a line with the upper edge of the rib f, and thus furnish a yielding support in front of the rib for the material being scored to rest upon, thus indicating to the attendant the proper position of the sheet.

The'stop or guide J serves to indicate and limit the distance of insertion of the material to be scored into the machine, so thatwhen properly set the scores will always be made in the proper place in the sheets, and the front edge or face of the stop or guide is formedwith the projections I) b, leaving considerable spaces between them, which spaces form clearances or chambers to receive any trash that might collect on the table and obstruct the proper facing of the edges of the sheets against the guide or stop.

It will be understood that I do not confine myself to the particular construction and arrangement of the parts of my new and improved scoring-machine herein shown and described, as various changes might be made and not depart from the principles thereof which constitute my invention.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with the compressinghead D, of the cam-wheels A A, having the gutters a a, with successively-inereasin g swells 15 jj, and the bars E E, having end studs or rollers d d fitting said gutters, whereby the compressor is made to give successively harder blows, as described.
